| Abstract: | Extraction conditions of flavonoids from longan leaves using one factor experiment and orthogonal experiment were studied. The results showed that the opimum conditions were that extraction time was 3 h, ratio of material to solvent was 1：25, ethanol concentration was 50 % and extraction temperature was 80℃. |
